Review known spawning areas for pelagic and invertebrate species, with the aim of evaluating these sites as candidate spawning refugia. 2. Evaluate each of the project’s habitat demonstration sites as potential juvenile/pre-recruit refugia for significant demersal species. Rationale for the Two-Track Approach to the Identification of Fisheries Refugia The two main life history events for fished species are reproduction and recruitment. It was noted by the RSTC that both of these events involve movement between areas, and some species, often pelagic fishes, migrate to particular spawning areas. It was also noted that many species also utilise specific coastal habitats such as coral reefs, seagrass, and mangroves as nursery areas. In terms of the effects of fishing, most populations of fished species are particularly vulnerable to the impacts of high levels of fishing effort in areas and at times where there are high abundances of (a) stock in spawning condition, (b) juveniles and pre-recruits, or (c) pre-recruits migrating to fishing grounds.

  • Early Development Stages of Two Secutor Species
    Bangladesh]. Fish. Res., 6(1), 2002: 19-28 Early developmental stages of two Secutor species (Family: Leiognathidae) collected from the Bak-khali river estuary of the Bay of Bengal, Bangladesh M. M. Islam, M. M. Haque* and M. A. Hossain1 Department of Fisheries Management, Bangladesh Agricultural University, Mymensingh 2202, Bangladesh 1Bangladesh Fisheries Research Institute, Mymensingh, Bangladesh *Corresponding author Abstract Early developmental stages of two Secutor species, Secutor insidiator (Bloch) (11.9-36.0 mm standard length, SL) and Secutor ruconius (Hamilton-Buchanan) (14.0-33.0 mm SL) collected by ichthyoplankton net from the Bak-khali river estuary of the Bay of Bengal, Cox's Bazar, Bangladesh are described and illustrated. All of the fins with supporting spines and rays were present in the smallest collected sizes of both species. With growth of the specimens, significant changes in melanophore patterns were found. S. insidiator is similar to S. ruconius in having upward protracting mouth parts and body colouration, but can be distinguished easily by its more elongate body shape (body depth 38-47% of SL compared with 46-52% of SL in Secutor ruconius). Both the species occurred round the year from August 1998 to July 1999. The surface water temperature and salinity during the study period varied from 22.0-32) C and 10-37 ppt respectively. Key wards: Early ontogeny, Bay of Bengal, Secutor Introduction Members of the family Leiognathidae are small fishes (Jones 1985), shoaling, bacterially bioluminescent and characterized by having silvery, laterally compressed bodies, highly protrusible jaws and locking median fin spines (Seigel 1982); top of head with bony ridges and nuchal crest; single dorsal fin with 8 spines and 16 rays, and anal fin with 3 spines and 14 rays; first dorsal and anal spines minute, second spines usually longest; body colour silvery, upper half of the body usually with so:::ne dusky patterning (Haneda and Tsuji 1972).

Das Simon, 3Aziz Arshad, 2Che A. R. Mohamed, and 2Gires Usup 1 Department of Fisheries Science and Aquaculture, Faculty of Agrotechnology and Food Science, Universiti Malaysia Terengganu, Terengganu, Malaysia; 2 Marine Ecosystem Research Centre, Faculty of Science and Technology, Universiti Kebangsaan Malaysia, Selangor, Malaysia; 3 Department of Aquaculture, Faculty of Agriculture, Universiti Putra Malaysia, Selangor, Malaysia. Corresponding authors: Y. G. Seah, [email protected] and A. G. Mazlan, [email protected] Abstract. The taxonomy of leiognathid species has changed drastically as a result of revisions carried out in recent years. During the same period, new species have also been described. In this study, a taxonomic review and update of leiognathid species present in Malaysian waters was carried out. Leiognathid specimens were collected from the coastal waters of Peninsular Malaysia. All specimens were examined for their internal and external morphological features and osteological features. The leiognathids of Malaysia reviewed here comprised at least 22 species. Malaysia thus has one of the richest assemblages of leiognathid species in the world. Equulites laterofenestra (Sparks & Chakrabarty, 2007), Leiognathus robustus Sparks & Dunlap, 2004, and Nuchequula mannusella Chakrabarty & Sparks, 2007 are new records in Malaysian waters. Some previously described species from Malaysia were erroneously identified. These include specimens misidentified as Equulites rivulatus (Temminck & Schlegel, 1845), Gazza achlamys Jordan & Starck, 1917, and Nuchequula nuchalis (Temminck & Schlegel, 1845). E. rivulatus and G. achlamys have been recorded in the Western Pacific but these species have not been encountered in Malaysia or in collections held in Malaysia.

Comparisons are made among species in a Principal Components Analysis. Sri Lanka’s proximity to the type localities of many inadequately described ponyfish species makes it ideal for the rediscovery and redescription of populations consistent in features with those from the original descriptions. Many ponyfish species were described over a hundred years ago (sometimes over 200 years ago) without designation of type material and using vague and non-apomorphic features. The descriptions made here will allow for comparison with those earlier descriptions and leiognathid specimens from localities throughout their range. These comparisons may lead to the discovery of new species and to a better understanding of the relationships within the group. In addition, Aurigequula Fowler, 1918 is resurrected from synonymy with Leiognathus Lacepède, 1802 to replace a previously established invalid name. Aurigequula comprises, A. fasciata and A. longispinis.

Corresponding author: Asriyana, [email protected] Abstract. Trophic ecology can be used to determine feeding strategy and indirect energy flux within a fish community, and also explains the trophic interaction between different fish species in a food web. This research was aimed to study the trophic ecology of twobloch ponyfish Nuchequula blochii in Kendari Bay, Southeast Sulawesi. The samples were collected monthly during October 2016 to May 2017 using bottom gillnets with mesh size ¾, 1, 1¼, 1½, and 2 inches. Food composition was analysed using Preponderance Index whereas feeding strategy was determined using Costello method modified by Admunsen. There were 247 fish with the total length and weight ranged from 45.0-119.0 mm and 5.0- 31.4 g, respectively. The fish were categorized into 3 groups based on the length and weight sizes. The length sizes were classified into small size (45.0-69.7 mm), medium size (69.8-94.3 mm) and large size (94.4-119.0 mm). Twenty three species of organisms were found in the digestive system of the twoblotch ponyfish dominated by the phytoplankton genus Thallasiothrix. There was a significant difference in the food composition of the fish based on the size groups. Small size fish fed on 9 food organisms dominated by the phytoplankton group.

  • 3.6 Fish Fauna
    3.6 Fish Fauna 3.6.1 Introduction Fish are one of the major sources of high-quality protein, providing about 16% of animal protein for human consumption around the world /18/. The fish are either caught in the wild or raised through fish farming or aquaculture. The distribution pattern of fish depends on behavioral response to refuge availability provided by structural complexity /19, 20/ and available resources i.e. food /21, 22/ or they may be due to interactions of predation and competition /21, 23/. In Kuala Linggi, Malacca is one of the main fisheries areas for many of the fishermen there. Fishermen from Tanjung Selamat, Tanjung Agas, and Kuala Sungai Baru were use fish nets, longline and fish traps (bubu). The catch is either consumed or sold to the market. One of the main factors contributing to the high abundance of fish in the area may be due to the mangrove forest, which acts as nursery for juvenile fishes /24, 25/. In addition, the structural complexity of the mangrove, due to the roots and branches, provides a refuge, especially for juvenile fish /26,27, 28/ In conclusion, the high productivity in both mangrove forests and seagrass beds provides greater availability of food for juvenile fishes than other habitats, either directly as detritus or indirectly through the structural complexity that attracts greater numbers of prey items. High abundance of invertebrates is usually found in vegetated areas /29/ which becomes suitable prey for these juveniles. Therefore, it is important to conserve these habitats, which is to ensure the continuous supply of these fishes.

  • Phytoplankton Fuel the Energy Flow from Zooplankton to Small Nekton in Turbid Mangrove Waters
    Vol. 469: 7–24, 2012 MARINE ECOLOGY PROGRESS SERIES Published November 26 doi: 10.3354/meps09997 Mar Ecol Prog Ser Phytoplankton fuel the energy flow from zooplankton to small nekton in turbid mangrove waters L. L. Chew1,2, V. C. Chong1,2,*, K. Tanaka3, A.

Despite the high turbidity and large amounts of detrital material in the water column, the study reveals that phytoplankton fuel the energy flow to zooplankton and small nekton in mangrove-fringed estuar- ies. The stable carbon isotope (δ13C) values and C/N ratios (7.2 to 8.2) of fine seston (<63 µm) in estuaries indicate the importance of phytoplankton (δ13C: −22.8 ± 0.6‰) to zooplankton (−23.4 to −18.2‰) nutrition, with a trophic contribution of 70 to 84%, whereas mangroves contributed <11%. In adjacent coastal waters, zooplankton (−19.2 to −15.1‰) grazed on both phytoplankton and benthic diatoms (−17.3 ± 1.24‰). Aggregated or mucilage-secreting diatoms (giving depleted δ13C values) were abundant in the estuarine seston, but did not appear to be consumed or assimi- lated by zooplankton. Stomach content analysis showed significant consumption of zooplankton, especially copepods (mainly Pseudodiaptomus annandalei), sergestids (Acetes spp.) and mysids by young and small nekton (<14 cm standard length) in mangrove estuaries, while δ13C values indicate the increasing importance of mangrove carbon to juvenile fish nutrition (8 to 44%).

    ANNOTATED BIBLIOGRAPHY OF THE SILVERBELLIES (PISCES: FAMILY LEIOGNATHIDAE) P. S. B. R. James M. Badrudeen V. Edwin Joseph CMFRI SPECIAL PUBLICATION Number 50 ICAR CENTRAL MARINE FISHERIES RESEARCH INSTITUTE (Indian Council of Agricultural Research) P.B. No. 2704, Dr. Salim AH Road, Cochin - 682 031, India APRIL, 1992 Published by Dr. P. S. B. R. James Director Edited by Dr. K. J. Mathew Dr. P. Bensam Mr. K. N. Krishna Kartha and Mr. K. Kanakasabapathy PREFACE Fishes of the family Leiognathidae, popularly called silverbellies, ponyfishes, slipmouths and toothponies are small to medium sized fishes living at the bottom in shallow coastal waters. They are widely distributed in the Indo-Pacific region. These fishes are captured in several types of fishing gear including bottom trawls, shore seines, gillnets, bagnets etc. Some species occur in dense schools offering great potentialities for commercial exploitation, especially along the coasts of India and Sri Lanka. A few species enter brackishwaters and estuaries. Being small and scanty of flesh, they are consumed very little in fresh condition but mostly sun dried or salt cured. As such they are an important source of food and fish meal. Till date 21 species of the family are on record in their entire range of distribution. Literature on various aspects of individual species on their taxonomy, distribution, biology, fishery etc. is very extensive, widely scattered and published in various scientific and other journals from several countries. Pauly et al. (1981: ICLARM Bibliographies, 2, 62 pp.) covered 941 references on this group in an annotated bibliography. It was felt necessary to supplement this list with all those publications not covered in it as well as to include the recent ones after that date.

Hossain1 Department of Fisheries Management, Bangladesh Agricultural University, Mymensingh 2202, Bangladesh 1Bangladesh Fisheries Research Institute, Mymensingh, Bangladesh *Corresponding author Abstract Early developmental stages of two Secutor species, Secutor insidiator (Bloch) (11.9-36.0 mm standard length, SL) and Secutor ruconius (Hamilton-Buchanan) (14.0-33.0 mm SL) collected by ichthyoplankton net from the Bak-khali river estuary of the Bay of Bengal, Cox's Bazar, Bangladesh are described and illustrated. All of the fins with supporting spines and rays were present in the smallest collected sizes of both species. With growth of the specimens, significant changes in melanophore patterns were found. S. insidiator is similar to S. ruconius in having upward protracting mouth parts and body colouration, but can be distinguished easily by its more elongate body shape (body depth 38-47% of SL compared with 46-52% of SL in Secutor ruconius). Both the species occurred round the year from August 1998 to July 1999. The surface water temperature and salinity during the study period varied from 22.0-32) C and 10-37 ppt respectively.

This study aimed to investigate diet preferences of small fishes in a shallow coastal lagoon through analysis of their stomach contents. The 24 hours samplings was done during high tide at selected stations; mangrove areas and seagrass areas, both located at coastal lagoon of Setiu, Terengganu (N 5o41.75’ E 102o42’ to N 5o 42.5’ E 102o41’). The small fishes were caught using seine nets (0.5 cm2), while the zooplanktons were collected using Kitahara zooplankton net (110 microns) then were preserved. All items found in the stomach were compared with the composition of the zooplanktons obtained from the water samples. During the sampling time, 10 species of small fishes were caught. There were higher number of fishes and zooplanktons caught from the seagrass areas than the mangrove areas. Nonetheless, diversity of zooplankton was higher in the mangroves. Overall, the number of harpacticoid was higher than all other food items found in the stomach of fishes caught from both areas despite the high number of calanoid copepods found in the lagoon. Keywords: Copepods, diet, Setiu Lagoon, small fishes 1 Introduction Zooplankton is an important community in aquatic ecosystem for energy transfer from primary producer to fishes [1].
